IMPROVEMENT IN CAR-COUPLINGIS.`

Specification forming part of Letters Patent No. 145.228, dated December2, 1873; application tiled l May 13, 1873.

To all 'whom t may concern Be it known that we, J oHN F. MULLowNY, ofPittsburg, in the county of Allegheny and State of Pennsylvania, J AMESCOPE, ot' Connellsville, in the county of Fayette and State ofPennsylvania, and SIDNEY R. Bnoons, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Car-Coup 1ers; and we do hereby decla-re that thet'ollowing is a full, clear, and exact description thereof, that willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings and to theletters of reference marked thereon, which form a part ot' thisspecitcation.

In the drawings, Figure lis a perspective view of our improvement asapplied to passenger-cars. Fig. 2 is a perspective view of ourimprovement as applied to freight-cars. Fig. 3 is a perspective view,showing the bottom of aca-r with our frei ght-car coupling attached.

This invention has relation to automatic car-couplings 5 and consists inthe construction and novel arrangement of devices for receiving andholding the heads of the barbed or arrow-shaped coupling-links, and ofthe devices for releasing the latter to eiiect the uncoupling of thecars, all substantially as here inafter described.

In the accompanying drwings, which illustrate our invention as adaptedto use on freight and passenger cars, A designates the body of the car,and B the barbed couplinglinks. O C designate converging plates attachedto rods or arms, which are hinged or pivoted to the end of the car, andbraced by means of hinged brace-rods d, connected to the bottom partsofthe car.

The inner ends of the couplinglinks are secured, in any convenientmanner, underneath the car, while the barbed ends project some distancebeyond the end of the car, as shown, the shank passing between theplates O.

In coupling, the head of the link of one car enters the space betweenthe two plates C of the approaching car, and separates said plates so asto pass behind them, after which the plates return to their originalpositions, and thereby secure the link. The plates are caused to resumeand retain sufficiently their vertical positions by the weights b uponthe upper ends of the rods b', to which the plates are attached.

D designates plates attached to the rods b of 'the passenger-car whichis represented in Fig. 1. The plates D being located above the plates Oenable the latter to be separated readily, through the medium of the camE, actuated by the lever F, which extends upward through a slot in thecar-platform.

The mechanism for uncoupling freight-cars is somewhat modied, so thatthe uncoupling may be ci'ected from the sides of the car. The plates Dare therefore dispensed with, and instead thereof the pivoted horizontalarms d' employed. The latter are pivoted to the under side of thecar-body, and pass forward between the rods b' above the plates O.

A transverse bar or lever, D', is pivoted to the under side of the carnear the rear ends ot' the arms d', and is provided with studs F',which, when the bar or lever D is moved, spreads the arms d' apart attheir forward ends, and causes them to swing apart the plates O, thusreleasing the link.

It is obvious that the plates C ODD are not absolutely essential to ourinvention. Depending rods or bars, whether inclined or otherwise, willserve to admit the links, while the cam E will operate against the bars,and serve to make the proper change for uncoupling.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

1. The plates C, hinged rods b', and weights b, combined substantiallyas shown and described.

2. The cam E and lever F, in combination with the plates C D and hingedrods b, substanti-ally as and for the purpose specied.

3. The transverse pivoted bar D', having the studs F', in combinationwith the arms d' and hinged plates C, substantially as and for thepurpose specified.

In testimony that we claim the foregoing we have hereunto set our handsthis 28th day of April, 1873.
